PE should be optional in school. Sports are aerobic, but they aren't structured to "educate." Furthermore, they nurture an artificial social structure based on coordination rather than character. Many children are in home school because of this.
Even if PE did serve its intended purpose, it is not the place of government to mandate civilian fitness. The 14th Amendment guarantees liberty to all law-abiding citizens, even the right of parents to let their kids be plump.
